Mrs. Simmons gave a history test worth 92 points. There were only two types of questions on it: 2-point true/false questions and
SVETLANKA909090 [29]

Answer:

There are 8 true/false questions and 26  fill-in-the-blank questions.

Step-by-step explanation:

Let "t" be the number of 2-point true/false questions and "f" the number of 5-point fill-in-the-blank questions.

Mrs. Simmons gave a history test worth 92 points. Symbollically,

2 t + 5 f = 92   [1]

There were a total of 34 questions in the test. Symbollicaly,

t + f = 34

t = 34 - f   [2]

If we replace [2] in 1, we get

2 (34 - f) + 5 f = 92

68 - 2 f + 5 f = 92

3 f = 24

f = 8

We replace f = 8 in [2],

t = 34 - 8 = 26

There are 8 true/false questions and 26  fill-in-the-blank questions.

What is the value of x? <br><br><br><br> x =
Alexandra [31]
The formula we need is this one: EC(EC+CD)=EB(EB+BA).  Filling in accordingly, we have x+4(x+4+1)=x+1(x+1+11).  Simplifying that we get (x+4)(x+5)=(x+1)(x+12).  We will FOIL both sides to get x^2+9x+20=x^2+13x+12.  Combining like terms gives us this simplification: 0=4x-8.  If we factor out the common 4, we have 0 = 4(x-2).  By the Zero Product Property, eitheer 4=0 or x-2=0.  Well obviously, 4 does not equal zero, so x-2 = 0, and x = 2.
